Copying ".."

[Wayne Davison]

I just noticed that copying ".." with rsync copies the directory by
name, resulting in the destination files being written out one directory
higher than expected.  For instance,

    rsync -av .. /var/tmp/save-dir/

That would copy everything from the parent dir into /var/tmp, not
/var/tmp/save-dir.  Ouch.

I don't think that anyone depends on this anti-intuitive behavior,
right?  Attached is a patch that makes the above command behave as
if "../" had been specified for the source.
